If you thought the Grand Canyon was…well Grand, wait until you check out this massive canyon on Mars.  This Canyon is about 11 times larger than the Grand Canyon and clearly shows evidence that there was once water on Mars.  At a whopping 2,500 miles across the surface of Mars and a Depth of 5.6 miles, it would make any man afraid of heights if you were looking down.

Ok, maybe not every man, but it would certainly be an interesting site to see.  If you’re anything like me, you can’t help but wonder how can something this massive exist?

Clearly Mars had water on it once.  Perhaps it was at one point in the Habitual Zone of the Solar System?  Which might explain the mysterious structures found on Mars, such as the Pyramid and the Face.  I have no idea if those are real or not, but it does make you wonder.
